1. A utility company serves 50,000 households. As part of the survey of customer attitudes, they take the simple random sample of 750 of such households. The average number of television sets in sample households turns out to be 1.86, and SD is 0.80. If possible, find out a 95% confidence interval for average number of television sets in all 50,000 households. If this isn't possible, describe why not.
